Error! Unknown option '--help'
Usage:
gif2webp [options] gif_file -o webp_file
Options:
-h / -help ............. this help
-lossy ................. encode image using lossy compression
-mixed ................. for each frame in the image, pick lossy
or lossless compression heuristically
-near_lossless <int> ... use near-lossless image preprocessing
(0..100=off), default=100
-sharp_yuv ............. use sharper (and slower) RGB->YUV conversion
(lossy only)
-q <float> ............. quality factor (0:small..100:big)
-m <int> ............... compression method (0=fast, 6=slowest), default=4
-min_size .............. minimize output size (default:off)
lossless compression by default; can be
combined with -q, -m, -lossy or -mixed
options
-kmin <int> ............ min distance between key frames
-kmax <int> ............ max distance between key frames
-f <int> ............... filter strength (0=off..100)
-metadata <string> ..... comma separated list of metadata to
copy from the input to the output if present
Valid values: all, none, icc, xmp (default)
-loop_compatibility .... use compatibility mode for Chrome
version prior to M62 (inclusive)
-mt .................... use multi-threading if available
-version ............... print version number and exit
-v ..................... verbose
-quiet ................. don't print anything
Options (18)
| Option | Description | Source |
|---|
-o string | Specify the name of the output WebP file. | man |
-h, -help | Usage information. | man |
-version | Print the version number (as major.minor.revision) and exit. | man |
-lossy | Encode the image using lossy compression. | man |
-mixed | Mixed compression mode: optimize compression of the image by picking either lossy or lossless compression for each frame heuristically. | man |
-near_lossless int | Specify the level of near-lossless image preprocessing. | man |
-sharp_yuv | Use more accurate and sharper RGB->YUV conversion. | man |
-q float | Specify the compression factor for RGB channels between 0 and 100. | man |
-m int | Specify the compression method to use. | man |
-min_size | Encode image to achieve smallest size. | man |
-kmin int | | man |
-kmax int | Specify the minimum and maximum distance between consecutive key frames (independently decodable frames) in the output animation. | man |
-metadata string | A comma separated list of metadata to copy from the input to the output if present. | man |
-f int | For lossy encoding only (specified by the -lossy option). | man |
-mt | Use multi-threading for encoding, if possible. | man |
-loop_compatibility | If enabled, handle the loop information in a compatible fashion for Chrome version prior to M62 (inclusive) and Firefox. | man |
-v | Print extra information. | man |
-quiet | Do not print anything. | man |
